Yes, they are both the Whammy IV. I can't read on the bottom where either are made as there is velcro on both. Both of the wall-warts are the same brand but have different ratings.
His says:
input: 120V-60Hz 18W
output: 9V-1.3A
mine says:
input: 120V-60Hz 34W
output: 9V-2.1A
Here are some pics. Mine is on the left & his on the right.
I know it's hard to tell but mine is smooth & shiny & his is textured & more dull, deep red.
Thanks guys,
